ABSTRACT:
A method, system and apparatus for monitoring an environment for the occurrence of an unexpected event, such as monitoring a containment vessel's surroundings for the presence of the contained substance outside of the vessel due to a leak. The method detects the probability that a leak has occurred as opposed to mere natural fluctuations in substance concentration in the surrounding environment. A sensor near the vessel measures substance concentration. The concentrations sensed are transformed into a signal representing substance concentration outside the vessel as a function of time. A statistical analyzer then monitors the signal for specific patterns which indicate that a leak has occurred. Various algorithms are utilizable to determine the probability that a leak has occurred.
